There are bits and pieces of the Strapi class mentioned in various places all around the documentation, like strapi.db or strapi.entityservice. I’ve looked around and I can’t find an API reference anywhere. By reference I mean a single page where all the attributes of the Strapi object/class are listed with types and descriptions. The documentation is useful as it’s rich with tutorials, but frequently it’s a huge headache trying to find information about the API that’s exposed through the Strapi class that’s passed around everywhere.

Edit:
I found the reference for V3, though it’s severely lacking in any kind of detail. I am unable to find one for V4.
